An experiment is performed on plants to see how different liquids affect plant growth. Each plant in the experiment is given a different liquid; water, apple juice, or milk. Each plant has the same amount of soil, sunlight, and listens to the same music. Label each variable/group properly.

Groups:

(a) Constant

,

(b) Independent Variable

,

(c) Dependent Variable

,

(d) Control Group

• type of plant

• amount of sunlight

• type of soil

• plant that receives water

• type of liquid

• height of the plant
